Hi I have a countif formula as follows
=COUNTIF('Jan 10'!B:B,A2)
I have numerous tabs labelled with every month of the year "Jan 10" "Feb 10" etc.
I want the formula to look up the same range on every tab but when I put this formula in it gives a "#value" error.
=COUNTIF('Jan 10:Mar 10'!B:B,A2)
Does anyone know of a way to do this thanks!
